The National Weather Service warned Sunday that a dangerous, potentially record-setting heat wave will grip the eastern two-thirds of the United States this week and peak over the July 4 holiday — a forecast that points to soaring electric bills, strained power grids, and a costly stretch for any business that depends on people being comfortable enough to shop, work, and travel. The agency said a “heat dome,” a dome of high pressure that traps hot air like a lid, will push “feels like” temperatures to between 100 and 115 degrees across much of the country.

By late this week, more than 180 million Americans in the Midwest and East could face major or extreme heat-related health risks. Washington, Philadelphia, and New York City are all forecast to top 100 degrees, with daily records possible Thursday and Friday. Nights will bring little relief; lows in the Midwest and Great Lakes will not fall below the lower-to-middle 70s, while many urban areas could struggle to drop below 80.

The first business to feel the impact is electricity. When tens of millions of air conditioners run at once for days, power demand spikes toward record levels, forcing grid operators to work to keep supply ahead of demand. For households and businesses, that means higher utility bills as power companies rely on their most expensive backup generation during peak demand. Prolonged heat also raises the risk of localized outages, creating costly disruptions when cooling becomes a matter of health and safety.

Retailers see a heat wave as both a challenge and an opportunity. Demand typically surges for air conditioners, fans, portable coolers, cold drinks, and ice, with stores often selling out in the hardest-hit cities. At the same time, foot traffic at malls, outdoor markets, and neighborhood shopping districts tends to decline as people stay indoors, shifting more spending online and squeezing small businesses that depend on walk-in customers. Restaurants with outdoor seating and entertainment venues centered on outdoor activities also face slower business.

Employers with outdoor workforces are under the greatest pressure. The Occupational Safety and Health Administration recommends frequent breaks in shaded or air-conditioned areas during periods of extreme heat. While those precautions are essential for worker safety, they also slow construction projects, landscaping operations, delivery routes, and farm work, raising labor costs and delaying schedules during one of the busiest seasons of the year. Heat-related illnesses also increase workers’ compensation claims and lost workdays.

The timing makes the heat even more expensive because it coincides with one of the nation’s biggest spending weekends. The hottest temperatures are expected during a period filled with parades, cookouts, sporting events, and fireworks celebrations. Washington is also preparing for large crowds attending events marking America’s 250th anniversary. Organizers of outdoor celebrations now face the challenge of balancing crowd safety with attendance, and some daytime events could see lighter turnout as families wait for cooler evening temperatures.

Health care systems are preparing as well. Heat is the deadliest form of weather in the United States, claiming more lives each year on average than tornadoes, hurricanes, and lightning combined. Emergency-room visits for heat-related illnesses typically surge during prolonged extreme temperatures, while older adults and people with respiratory or heart conditions face the greatest risks.

The U.S. forecast follows a deadly stretch overseas that highlights the dangers. A historic heat wave across Europe recently resulted in roughly 1,000 excess deaths in France during a record-breaking period of extreme temperatures, according to French officials.

For now, forecasters continue to urge Americans to stay hydrated, spend time in air-conditioned spaces, check on elderly neighbors and vulnerable family members, and avoid strenuous outdoor activity during the hottest afternoon hours. The heat dome is expected to remain over much of the East, particularly along the Interstate 95 corridor, through the long Fourth of July weekend before gradually shifting west early next week.

Until then, the cost of staying cool is likely to become one of the week’s biggest economic stories, measured in higher utility bills, slower outdoor business, and reduced productivity across a large portion of the country.
